Pulley vs. Carta for a Dental Support Organization

A DSO managing two or three practices with founder-only equity has a simple cap table: the founders, maybe an early operator hire, and that's it. A DSO managing a dozen or more affiliated practices, each with its own dentist-owner and a management services agreement back to the DSO, has a materially more complex picture, one where you need the DSO-level cap table and a clean record of each affiliated dentist's rollover stake to stay separate but reconcilable.

The practical test: can you currently answer, without opening more than one file, exactly what percentage of the management company each founding dentist holds and when it fully vests? If the answer takes a phone call to your CPA or a search through old deal documents, that's a sign your current setup has already outgrown a spreadsheet.

Once a private equity investor buys into the management company, whether as a platform investment or a follow-on to fund more practice acquisitions, the DSO's cap table starts looking like an institutional one: preferred and common classes, a board, and reporting the fund's back office expects on a schedule. That's a different tool requirement than a founder-only DSO still adding its first few affiliated practices.

When a dentist sells their practice into the DSO, part of the consideration is often cash and part is DSO-level equity, a rollover meant to keep the founding dentist invested in the platform's future growth. That rollover equity should be tracked at the DSO level, separately from whatever ownership the dentist retains in their own professional entity, since the two represent different things: one is a stake in the platform, the other is the clinical entity structure that many states require.

Say a founding dentist takes seventy percent of their deal value in cash and rolls the rest into DSO-level equity vesting over four years. If they leave the network early, whether by choice or by underperformance, the rollover agreement needs to already answer what happens to the unvested portion, rather than leaving that for a negotiation nobody wants to have under pressure.

Pulley fits a DSO in its early stage, with founder equity and maybe one or two affiliated practices' rollover stakes, where the goal is a clean, fast setup before the structure gets more complex. If you haven't taken outside capital yet, this is usually the lower-friction starting point.

Carta fits a DSO that's raised institutional capital, is actively acquiring practices and issuing rollover equity to multiple founding dentists, or needs board-level and investor-level reporting on a regular cadence. Once a DSO is functioning as an acquisition platform, the cap table complexity usually outgrows a simpler setup fast.

Signs a DSO has outgrown a simple cap table setup:

• It manages a dozen or more affiliated practices, each with its own dentist-owner and a management services agreement back to the DSO.
• A private equity investor or other institutional capital has entered the management company.
• Rollover equity is being issued to multiple founding dentists as the DSO acquires practices.
• Your board or investors expect ownership reporting on a regular cadence.
• You are granting options to non-founder leaders and need a defensible 409A valuation behind each strike price.

A DSO granting equity or options to non-founder employees, a regional dental director, a VP of clinical operations, needs a defensible fair market value behind any strike price, the same as any other company issuing options. Because DSO valuations depend heavily on assumptions about future practice acquisitions and same-practice growth, work with a valuation provider who has done DSO or healthcare services work specifically, not a generalist unfamiliar with how these platforms are actually valued.

Write into the rollover agreement, before the acquisition closes, what happens to a founding dentist's equity if their own practice's production declines after joining the DSO, whether the stake is unaffected, subject to a clawback, or tied to a formula that adjusts with performance. DSOs that skip this step tend to face an uncomfortable negotiation later, when an underperforming practice's founding dentist still holds full equity while other founders' practices are carrying the platform's growth.

Outside investors, whether a private equity sponsor or a non-dentist operator, can hold equity and economic interest in the DSO management company, but they generally cannot hold ownership in the clinical professional corporations themselves. Keep this line clear in your cap table structure and in how you describe ownership to any new investor, since blurring it is exactly the kind of structural mistake that draws regulatory scrutiny in states that enforce corporate-practice-of-dentistry rules closely.
